At least for ansible 2.0.0.1 the command `ansible-galaxy --help` is inappropriate for testing if ansible is installed, as it yields an error:
```
vagrant@vagrant-ubuntu-trusty-64:~$ ansible-galaxy --help && echo "OK"
Usage: ansible-galaxy [delete|import|info|init|install|list|login|remove|search|setup] [--help] [options] ...
Options:
-h, --help show this help message and exit
-v, --verbose verbose mode (-vvv for more, -vvvv to enable connection
debugging)
--version show program's version number and exit
ERROR! Missing required action
```
In cd93721, I relied on a suprising combination of quotes to protect ssh
execution to strip the quoted path to the private key file.
Since any ssh command line argument can be passed via
`ANSIBLE_SSH_ARGS`, it is quite more readable and easy to rely on the
`-i` argument, which is not affected like `-o IdentityFile=...` and also
supports multiple occurences.

Finally fix#6671
Note that I decided to not squash both commits for better
documentation and traceability.
Surprisingly (to me at least), a simple quote enclosure was not enough
to fix the problem.
Caveat: the stringified ansible-playbook command logged in verbose mode
is wrongly formatted (no quotes are escaped).
Fix#6671
Like in the (remote) `ansible` provisioner, it is preferred to pass the
directory that contains the generated inventory file. This way, advanced
inventory usages can be achieved by adding more inventory files into the
same directory.
Related to #2103 and #6500

String and Symbol types are different when used as a Hash key. By
default the Vagrant machine names are set in Symbol format, but users
may write their `host_vars` entries with String keys. This is a very
simple way to ensure smooth experience, without having to coerce the
data types during the config validation (e.g. with a library like
Hashie, which is currently not in the Vagrant dependencies)

I missed to rename the refactored exceptions as AnsibleCommandFailed in
the guest-based parts. The lack of unit tests for these parts hurts...
on my agenda, I swear!
